A **rotation **may be a** transformation** in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.

Given points of triangle: S(1,1) , R (3, 4) and Q (7, 0).

Rotation 180° about the origin.

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.

A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as p. The angle adjacent to p is marked as o, and the other two angles inside the triangle are marked as m and n.

Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)

Step 2: m∠p + m∠o = 180 degrees (adjacent supplementary angles)

Step 3: Therefore, m∠m + m∠n + m∠o = m∠n + m∠p

Step 4: So, m∠m + m∠n = m∠p

In which step did the student first make a mistake and how can it be corrected? (4 points)

Step 2; it should be m∠o − m∠p = 90 degrees (complementary angles)

Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)

Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles)

Step 3; it should be m∠m + m∠n + m∠o = m∠o + m∠p

**Answer:**

Step 3; it should be angle m + angle n + angle o = angle o + angle p

**Step-by-step explanation:**

yes, the sum of the inner angles of the triangle, m, n, o must be 180°.

yes, the sum of supplementary angles (which the pair of inner and outer angles always is) p and o must be 180°.

so, step 3 wants to show that the sum of the 3 inner angles is the same as the sum of the inner/outer angle pair. m + n + o = o + p = 180.

but instead of o the student suddenly wrote n in the right side of the equation. and that is wrong. n + p can't be 180°, as both are inner angles, and that would make the third inner angle 0°, which is not really possible.

so, once n is replaced by o on the right side of the equating in step 3, all is correct again.

and step 4 is correct anyway (it fixed the mistake in step 3 of the original proof by another mistake, coming to the right conclusion just by coincidence), now that step 3 is corrected.

How to Find the Angle Measures Formed by Parallel Lines?The **angle measures** can be determined by using the special angle relationship between the angles involved when a transversal crosses two lines that are **parallel**.

9. x and y are **parallel** lines

m∠5 = 69°

m∠10 = m∠5 [alternate interior angles theorem]

m∠10 = 69° [substitution]

10. x and y are **parallel** lines

m∠9 = 115°

m∠6 = m∠9 [alternate interior angles theorem]

m∠6 = 115° [substitution]

11. x and y are **parallel** lines

m∠12 = 118°

m∠7 = m∠12 [alternate interior angles theorem]

m∠7 = 118° [substitution]

12. x and y are **parallel** lines

m∠4 + m∠11 = 180 [supplementary angles]

72 + m∠11 = 180 [substitution]

m∠11 = 180 - 72

m∠11 = 108°

13. m∠4 + m∠14 = 180 [supplementary angles]

114 + m∠14 = 180 [substitution]

m∠14 = 180 - 114

m∠14 = 66°

Write the equation of the line that goes between the two points (6, -5) and (2, 3).

The **equation **of the **line **that passes through points (6, -5) and (2, 3) is y = -2x + 7.

The formula for **equation **of **line **is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the data in the question;

Point 1 ( 6, -5 )

x₁ = 6y₁ = -5Point 2 ( 2,3 )

x₂ = 2y₂ = 3First, we determine the slope of the line.

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope m = ( 3 - (-5) ) / ( 2 - 6 )

Slope m = ( 3 + 5 ) / ( 2 - 6 )

Slope m = ( 8 ) / ( -4 )

Slope m = -2

Now that the value of slope is known, we determine the y-intercept 'b' by plugging the slope and one point into equation of line formula.

y = mx + b

-5 = (-2)(6) + b

-5 = -12 + b

b = -5 + 12

b = 7

Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.

y = mx + b

y = (-2)x + 7

y = -2x + 7

Therefore, the **equation** of the **line **is y = -2x + 7.

The following table shows the distance from the bus stop as a function of time:

Time (in minutes) Distance (in meters)

6 35

12 25

Find and interpret the meaning of the x-intercept in this scenario. (4 points)

(45, 0); the distance away from the bus stop

(27, 0); the time it takes to reach the bus stop

(45, 0); the time it takes to reach the bus stop

(27, 0); the distance away from the bus stop

The **x-intercept** is **(27,0). **The **time** it takes to reach the bus stop

We first find the equation between **time** and **distance **as a linear function by finding the slope and y-intercept from the table values.

If we write the** Time** as x-values and **Distance** as y-values, we get the points,

(0,45), (3,40), (6,35), (9,30), (12,25)

We can find the slope from these points considering two points (0,45) and (3,40)

Slope = 45-40/0-3 = -5/3

The y-intercept of the** function **is the value of f(x) at x = 0.

Here, from the table, when x = 0, y = 45.

So y-intercept = 45

Then the equation of **distance** in terms of **time** is,

y = -(5/3)x+45

The **x-intercept **is the x-value when y = 0.

So when y = 0,

0 = -(5/3)x+45

⇒ (5/3)x=45

⇒ x = 45x 3/5

⇒ x = 27

Therefore, **x-intercept** = **(27,0)**.

It is the** time** (in minutes) when **distance **= 0 meters.

So **x-intercept** is the **time** it takes to reach the bus stop.

The **slope **of **the **line, which can be stated as a** **numeric integer, fraction, or the **tangent **of the** angle **it forms **with **the **positive **x-axis, is the line's inclination with respect to the positive x-axis.

One of the significant forms used to express a straight line algebraically is the **two point form.**

Written as, y- y1= m (x- x1), where m is **slope**.

Given:

a line passes through the point (2, -2) and parallel to 5x-2y = 4

Now, writing the given **equation **of line in the **form **of **slope** **intercept** form

5x- 2y=4

2y = 5x -4

y= 5/2x -2

Here the slope is 5/2 and the **required** **line** will also have the **same slope** as parallel line.

then, m=5/2

Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation. (-8, -5); y= -3x + 5

**Step-by-step explanation:**

a parallel line must have the same slope (otherwise it cannot be parallel).

a slope-intercept form looks like

y = ax + b

"a" (the factor of x) is always the slope, "b" is the y-intercept (the y-value when x = 0).

so, we know from y = -3x + 5 that the slope of the new line is also -3.

to get b we use the coordinates of the given point :

-5 = -3×-8 + b = 24 + b

-29 = b

that means the line equation is

y = -3x - 29
